Accounting that’s Personal, Practical, and Precise.

Because you shouldn’t start a business without a good accountant.

I'm Maureen Miller.

Based in Oakland, CA, I bring over 20 years of experience helping clients build reliable financial systems rooted in clarity, integrity, and human connection. Whether you’re managing a nonprofit or launching your own small business, I help you make informed financial decisions — and tell the story of your numbers with confidence.

Let's see what we can accomplish together.

Services

Accounting & Bookkeeping

Smart Systems, Sound Books

From general ledger bookkeeping to 1099 filing and budgeting, I help nonprofits, small businesses, and entrepreneurs build reliable financial systems that support their mission. I specialize in setting up or refining accounting systems and training your team to use them with confidence — ensuring everything adds up when it matters most.

Training & Education

Accounting that makes sense (and cents!)

Teaching people who’ve always believed they “just don’t get accounting” is one of my favorite parts of this work. My signature workshop, Accounting 101, makes the basics of bookkeeping, financial statements, and accrual accounting approachable for everyone — from Executive Directors to small business owners, to bookkeepers.  Trainings can be tailored to your specific needs and industry.

Consulting

Straight Talk, Clear Numbers

Need help evaluating a new idea or navigating a financial challenge? Let’s talk it through. I offer practical consulting on a range of topics — from feasibility studies to organizational planning — with flexible options like hourly rates, retainers, or trades. Whether it’s a big decision or a quick check-in, I bring clarity to the conversation.

By The Numbers

66 Clients

Nearly 50% of my clients were engaged for short-term projects, such as accounting system set ups or consultations on limited-scope jobs.  I have served 35% of my client base for 3+ years and 15% of my client base for 6+ years.   

51% Client Referral

Over half of my clients come from referrals — nearly 10x the industry average — a reflection of the trust, results, and lasting relationships I build with every organization I serve.

23 Year in Business

In 23 years of practice, I’ve learned most clients don’t just need books managed — they need tools, coaching, and plain-English guidance to make their financial data truly meaningful.

Curious About How It Works?

"Do I need an accountant only during tax season?"

Nope — you need one year-round.

I am the accountant BEHIND the numbers you take to your tax professional to file your annual tax returns.   I help you understand your numbers, clean up your systems, and make better financial decisions — all year long.

"Can you help me improve my accounting system?"

Yes — and I’ll show you how to use it, too.

Whether you’re just getting started or need a cleanup, I specialize in setting up easy-to-manage accounting systems and training you (or your team) to use them confidently.

"I'm a nonprofit — can you help us with board reporting and finance strategy?"

Absolutely.

I’ve worked with nonprofits for over two decades, helping Executive Directors and boards feel confident in their numbers, budgeting processes, and compliance. I can also fill the gap between bookkeeper and finance manager when you need it.

"I don't understand my financial statements. Can you explain them to me?"

That’s one of my favorite things to do.

Understanding your financial statements is essential — not optional. I break things down in plain English so you can read, question, and use your financials to guide smart decisions.

"Do you offer training for my team or staff?"

Yes — and it’s more accessible than you think.

From Accounting 101 to custom trainings on accruals, allocations, and reconciliations, I help your team build the financial fluency they need to do their best work.

Clients Share Their Stories

Maureen is one of the most reliable and skilled financial professionals I have ever worked with. I have hired her in three different nonprofit organizations and foundations. She has built new accounting systems from the ground up, cleaned up messy books, and helped to ensure regulatory compliance across all levels. She has also worked with me to generate financial policies, prepare financial reports for my board, prepare paperwork for outside auditors, and hire and train finance staff.   I know every time I work with Maureen, my organization's accounting will be done right the first time.

Maureen helped untangle the chaos of my books and build new systems from the ground up. With her support, I’ve grown confident in my finances through every phase of my business—scaling, profit planning, and even debt recovery. She brings clarity, care, and a sense of humor to the numbers. I recommend her to everyone. She’s more than a CPA—she’s a true partner.
